    Stock fuel pressure at idle?

    I can't find my haynes book to look it up and I need to know what is the stock fuel pressure at idle.
    I think it's 37 psi at idle but I remember seeing a 30 psi number in the book but i can't remember what it was for.

    Does anyone know?


    I installed a new fuel filter and a new fuel pressure guage and it's reading 38 psi at idle.
    Thanks!

    30psi @ idle, 37psi @ WOT IIRC.

    FSM is a good source :P

    My fp at idle used to be 30 at idle - now it's 28 - any thoughts ? FPR or ? just leave it alone?
